Help with checking my grammar in this abstract of my project The literature points out that companies with better practices of corporate sustainability outperform their counterparts in several characteristics, such as better performance, lower risk and greater transparency in the disclosure of information. The disclosure of sustainable practices by companies around the world has been associated with a greater level of transparency, especially in environmental and social aspects (Siew, 2015) and a way to measure this transparency is through the earnings management (Martinez, 2008). Earnings management, according to Schipper (1989), is a purposeful intervention in the process of presenting the financial data of firms with the intention of obtain some private or personal gain. According to the literature, sustainable companies tend to do less earnings management (Kim, Park, & Wier, 2012). Considering these antecedents, the objectives of the paper are (a) to study the relationship between corporate sustainability and earnings management and (b) investigate the possible effects that the sustainability and transparency could have in the decisions making of the investors when they allocate their capital in a company in the stock market. To achieve the objective (a) there were developed tests and regressions in Brazilian open capital companies from the B3 for the period from 2010 to 2017. On the other hand, to achieve objective (b) was developed an experiment throughout an anonymous opinion survey applied to university students with knowledge and/or experience in finances and/or investments. The results of the investigation related to the objective (a) were that there are not a significant relationship between earnings management and corporate earnings. However, was found significant relationship between earnings management and size and ROA. The results of the investigation related to objective (b) indicates that sustainability and transparency do not affect the decision making of the investors. As the main limitations of the investigation stand out the disproportionality in the number of sustainable companies in the Brazilian stock market and the difficulty of treating the respondents in a homogeneous way regarding to socio-demographic factors.. For future works, it is suggested to relate other variables related to corporate sustainability as social responsibility or environmental impact to the analyses the issues previously exposed
